Cov impurities hauvdawb fused aluminatxiav txim siab nws lub neej, thiab nws qhov zoo cuam tshuam rau nws txoj haujlwm. Dawb fused alumina muaj impurities thaum lub sij hawm tsim khoom, feem ntau SiO2, Fe2O3, and TiO2; tsawg dua cov impurities, qhov zoo dua. Tus nqi ntawm Al2O3nyob rau hauv dawb fused alumina kuj ncaj qha qhia nws zoo, thiab impurities txiav txim nws lifespan.
Dawb fused alumina feem ntau yog siv los ua abrasive. Nyob rau hauv xyoo tas los no, nws tau siv dav hauv cov ntaub ntawv refractory, xws li hlau nuv castables, anhydrous slurry, corundum bricks, precast Cheebtsam, permeable cib, steel ladle bricks, thiab magnesia-alumina-carbon cib.
Dawb fused alumina kuj tseem siv tau los ua cov khoom siv refractory, tab sis impurities tuaj yeem cuam tshuam rau nws cov khoom refractory. Qee cov impurities hauv cov ntaub ntawv refractory yog yooj yim fusible, thaum lwm tus muaj cov ntsiab lus melting siab heev tab sis tuaj yeem tsim tau yooj yim fusible compounds thaum coexisting nrog lub ntsiab tivthaiv. Yog li ntawd, lub xub ntiag ntawm impurities feem ntau muaj zog fluxing nyhuv ntawm lub ntsiab tivthaiv.
Dawb fused alumina feem ntau yog siv los ua cov hmoov sib xyaw thiab cov hmoov zoo hauv cov ntaub ntawv refractory. Nws qhov zoo muaj xws li siab refractoriness, hnav tsis kam, erosion kuj, siab bulk ntom, thiab siab alumina cov ntsiab lus. Nws yog tsuas yog siv nyob rau hauv siab - alumina thiab alumina refractory cov ntaub ntawv. Thaum siv nyob rau hauv cov khoom refractory, nws kuj qhia tau hais tias siab load softening kub thiab siab - kub ntim stability.
